Study Description

Brief Summary:

The purpose of this research study is to compare the effects of cannabidiol (CBD), tetrahydrocannabinol (THC), or both, on sleep and pain in persons with multiple sclerosis (MS). Little is known about how CBD and/or THC may help sleep, reduce pain, or perhaps even treat pain through better sleep.

Condition or disease	Intervention/treatment	Phase
Multiple Sclerosis; Sleep; Pain	Drug: Cannabidiol (CBD); Drug: Tetrahydrocannabinol (THC); Drug: Placebo CBD; Drug: Placebo THC	Phase 2

Study Design

Arms and Interventions

Arm	Intervention/treatment
Experimental: Cannabidiol (CBD); Epidiolex® doses will be 0.5 mL twice daily during the first seven days of active treatment and 1 mL twice daily (b.i.d.) for the remaining days of treatment. PLUS Placebo Tetrahydrocannabinol (TCH) capsules which contain no active ingredients. Matching placebo capsules will be taken twice per day in the same schedule and manner as active dronabinol.	Drug: Cannabidiol (CBD); Epidiolex® doses will be 0.5 mL twice daily during the first seven days of active treatment and 1 mL twice daily (b.i.d.) for the remaining treatment.; Other Name: Epidiolex®; Drug: Placebo THC; Placebo capsules will be taken twice per day in the same schedule and manner as active dronabinol.
Active Comparator: Tetrahydrocannabinol (THC); The drug dose will be 2.5 mg b.i.d. during the first seven days of active treatment, and 5 mg b.i.d. for the following days of active treatment. PLUS Placebo CBD (A matching placebo oral solution to Epidiolex® will be used that consists of all of the excipients in the active solution without the cannabidiol component). The placebo will be dosed in the same schedule and manner as active Epidiolex®.

Active Comparator: CBD + THC	Drug: Cannabidiol (CBD); Epidiolex® doses will be 0.5 mL twice daily during the first seven days of active treatment and 1 mL twice daily (b.i.d.) for the remaining treatment.; Other Name: Epidiolex®; Drug: Tetrahydrocannabinol (THC); The drug dose will be 2.5 mg b.i.d. during the first 7 days of active treatment, and 5 mg b.i.d. for the following treatment.; Other Name: Marinol®, dronabinol
Placebo Comparator: Placebo CBD + Placebo THC	Drug: Placebo CBD; Placebo solution will be taken twice per day, using the same dosing regimen as described for Epidiolex®.; Drug: Placebo THC; Placebo capsules will be taken twice per day in the same schedule and manner as active dronabinol.

Outcome Measures

Primary Outcome Measures :

1. Mean change in sleep bout length [ Time Frame: Baseline, 12 weeks ]
   Measured with in-laboratory polysomnography, reported as average length of continuous bouts of sleep, for each sleep stage and total sleep (in minutes).
2. Change in Walsh Spectral Entropy [ Time Frame: Baseline, 12 weeks ]
   Measured with in-laboratory polysomnography, computed from EEG sleep stage data to quantify hypnogram regularity (dimensionless, values range from 0-1)
3. Change in Transition Entropy [ Time Frame: Baseline, 12 weeks ]
   Measured with in-laboratory polysomnography. Entropy measure computed from sleep stage transition matrix that quantifies hypnogram regularity (dimensionless, values range from 0-1)
4. Change of center of activity [ Time Frame: Baseline, 12 weeks ]
   Measured with in-laboratory polysomnography. Weighted mean temporal location over the night of all 30 second epochs scored as N3 and Rapid eye movement (REM) sleep
5. Change in sleep rhythmicity [ Time Frame: Baseline, 12 weeks ]
   Measured by actigraphy. Probability of being in the same sleep/wake state 24h apart
6. Change in sleep regularity [ Time Frame: Baseline, 12 weeks ]
   Measured by actigraphy in hours.
7. Change in sleep continuity and duration [ Time Frame: Baseline, 12 weeks ]
   Measured by actigraphy in minutes to obtain time in wakefulness after sleep onset (WASO) and total sleep time.
